BASE (Building, Antenna, Span, and Earth) jumps are done without a reserve
because they would be useless. (Main didn't open? Prepare to die, or get
seriously b0rke.) BASE jumpers prefer reserve/emergency chutes for obvious
reasons: they don't want to die.

Aren't most BASE jumps done without a reserve? Do BASE jumpers prefer
the reserve square or the sport chute (since control into tight LZs is
a consideration)?

Just trying to get educated since we appear to have a group of folks
with useful information.
